Bringing down cow flatulence can reduce the presence of greenhouse gases. So believe a group of scientists from New Zealand and Australia, currently working on a multi-million dollar research

Heat wave in the US, Europe As the us experiences a heat wave unprecedented in the past 57 years, its largest city New York has declared a state of emergency for the first time. Following

Fossil fuel burning releases about 25 Pg of CO2 per year into the atmosphere, which leads to global warming (Prentice et al., 2001). However, it also emits 55 Tg S as SO2 per year (Stern, 2005), about half of which is converted to sub-micrometer size
sulfate particles, the remainder being dry deposited. Recent research has shown that the warming of earth by the increasing concentrations of CO2 and other greenhouse gases is partially countered by some backscattering to space of solar radiation by

This article examines Bus Rapid Transit (BRT) as a near-term strategy for reducing CO2 emissions in a typical medium-sized U.S. city. The paper compares the expected CO2 emissions from three scenarios to meet the city's growth in work trips by 2011: a no-build option that relies upon private automobiles and a diesel bus fleet; building a light rail (LRT) system; and building a BRT system using 40-ft or 60-ft low emission

The European Union (eu) has decided that all flights taking off from and landing in its territory to buy carbon credits to offset greenhouse gas (ghg) emissions. The implementation of the decision

US greenhouse gas emission shoots up

This article examines the question of how to interpret a relationship between income and carbon emissions in a country (the environmental kuznets curve [EKC] for carbon). A very simple and graphical structural model of an EKC is developed, and the problems of applying the concept to carbon are discussed.
